What Is The Aggregate in The Brake Pad

What is the aggregate in the brake pad? As many as ten kinds of raw materials are added to a brake pad. It is mainly composed of friction materials. Friction material is only the primary component, also called aggregate. In 1972, the World Medical Seminar confirmed that asbestos fiber can affect human health. In the same year, governments around the world implemented regulatory restrictions on asbestos dust. Advantages: low price; Defect: harmful to human body, slow heat dissipation;
Semi-metal brake pads are made of crude steel fiber as an important mixture, and have some magnetic defects: simple rust, simple noise, low temperature. The brake disc is more worn, and the braking force is required more; Advantages: good thermal conductivity, suitable for high-temperature braking;
The metal composition of the metal brake pad is reduced, and some of the defects of copper powder and steel velvet are used. The wear resistance is low. The advantages are good thermal conductivity and heat dissipation, low noise, good braking comfort, and stable conflict coefficient;
The organic brake materials of Nao ceramic brake pads without asbestos mainly use glass fiber, cool aromatic polyester fiber or other fibers (carbon, ceramic) as reinforcement materials, and generally use ceramic brake pads. Its function mainly depends on the type of fiber and other additives. The cost of ceramic brake pads is very high. There is no pure ceramic brake pads in China's after-sales market. Pure ceramic brake pads are mainly used for racing.
Powder metallurgy brake pads and carbon carbon brake pads are mainly used for high-speed railway and aircraft. The advantages and disadvantages of conflict data are mainly reflected in conflict function, fatigue resistance and temperature, sensitivity to pressure and speed, wear resistance and noise. The better the conflict data, the better the conflict function under different temperatures, pressures and speeds. In other words, its function should not change much at low or high temperature. The better the conflict data, the less likely the brake will shorten after repeated braking, which will make the "brake pedal feel" good.
Better materials can also reduce wear and noise. Select a pair of high-performance brake pads to ensure effective braking effect and driving safety in different environments!
